Eaton 727802 Pneumatic Hose Coupler 3/8 Inch Brass

Product Description

The EATON 727802 is a brass pneumatic hose coupler designed for use in compressed air systems requiring reliable quick-connect functionality. With a 3/8-inch body diameter and 3/8-inch hose inside diameter, this coupler follows the Industrial Interchange standard, making it compatible with a wide range of pneumatic tooling and air supply setups found in shop and field environments. Brass construction provides corrosion resistance and durability under repeated connect-disconnect cycles. This coupler is installed by HVAC technicians, plumbers, industrial maintenance trades, and general contractors working with compressed air lines.

This coupler suits residential and light commercial applications where Industrial Interchange fittings are the shop standard. Common install scenarios include connecting pneumatic tools, air hoses, and compressor lines in service vans, shops, and mechanical rooms. The 3/8-inch sizing is a frequent choice for mid-flow air tool circuits. Each package contains 2 couplers, making it practical for stocking pairs for dual-outlet setups or replacement of worn fittings in an existing pneumatic system.

Key Features

• Brass body provides corrosion resistance and long service life in compressed air environments
• 3/8-inch body diameter and 3/8-inch hose inside diameter for common mid-flow pneumatic circuits
• Industrial Interchange standard for broad tooling compatibility
• Quick-connect coupler design allows fast hose changes without tools
• Sold in a package of 2, convenient for stocking or paired installations

Compatibility

Designed as an OEM-style replacement or add-on coupler for pneumatic air systems using Industrial Interchange standard fittings with 3/8-inch hose inside diameter connections.

Installation Notes

Depressurize and bleed the air line completely before removing or installing any pneumatic fittings. Inspect the coupler body and o-ring sealing surfaces for debris before connecting. Thread sealant or PTFE tape may be required on threaded inlet connections depending on the fitting interface. This work is typically performed by trained maintenance or HVAC service technicians following applicable shop safety practices.
